Cannabis Stability Chambers – PH Series

The Darwin Chambers PH Series Cannabis Stability Chambers are designed for performance specifications exceeding FDA and ICH requirements. For GMP studies, ultrasonic humidification provides excellent humidity control and avoids hot spots during mapping. Thermoelectric cooling provides more stable temperature control than equivalent refrigeration systems. All PH series chambers incorporate inherent cooling redundancy, quiet operation, simple serviceability and excellent reliability. The PH Series from Darwin Chambers was introduced nearly 15 years ago as the first large capacity thermoelectric cooled pharmaceutical stability testing chamber. Hundreds of stability chambers are presently in use by many pharmaceutical, cosmetic, nutraceutical, medical device, and research companies around the world. The advantages of these chambers for stability or shelf life testing are substantial. We build chambers to meet very specific requirements in a wide variety of industries. The PH Series chambers are our most popular offering for good reasons. These chambers produce exacting results and we provide support for them with timely quoting, quick lead times, reliable insulation, trusted validation services, and superior product support in the future.
